ELECTRIC-LAMP ATTACHMENT FOR GAS-FIXTURES.

SPECIFICATION forming part of Letters Patent No. 400,658, dated April 2,1889.

Application filed J'u11e 12, 1888.

- piece and socketpiece adapted to be used in conjunction with eachother, and together constituting a convenient attaching device, as ismore fully set forth in the following specification, reference being hadto the accompanying drawings, forming part thereof, in

Figure 1 is a perspective view of the arm. Fig. 2 is a perspective viewof the socket. Fig. 3 shows in central section the arm and socketcombined and in place, also a portion of a gas-fixture. 1

A represents a portion of an ordinary gasfixture having a screw-nipple,a, adapted to receive the gas-burner, but upon which I firmly screw thesocket-piece B, which is tubular, the inner portion of the lower endbeing suitably screw-threaded, to adapt it for the purpose, and theouter portion of the upper end being formed into a suitablescrew-threaded nipple, b, to receive the gas-burner. At the base of thenipple b, on this socket B, is formed a short neck or collar, 0, havingthree or more angles or corners, and at its base shoulders c c areformed by the circle arcs of the socketbody. This neck 0 is adapted toreceive the eye end of the arm D, which arm, as is shown by Fig. 1, isprovided with a screw-threaded nipple, d, at one end, adapting it toconnect an electric lamp. This nipple d has an opening, E, extendingthrough it, through which the conducting-wires are led into the lamp.

The other end of the arm D is formed broad and fiat and pierced with anangular opening or eye, 6, adapted to fit snugly on the neck 0 of thesocket-piece B. The end 6 of the arm' screwed on the nipple b, willsecurely clamp and hold it.

Serial No. 276,888. (No model.)

It will be seen that the arm D may be placed in any directioncorresponding with one of the angles on the neck of the socket-piece B,so that no matter what direction it is desired to have it project itwill require no more than one-eighth of a turn of the socket-piece toproperly set it. v

I am aware that an arm having a nipple at one end for attaching a lampand a socket to screw on the nipple of a gas-burner at the other end hasbeen in use; but this has been made all of onepiece, and the resultisthat it is inapplicable to many gas-fixtures, because the projectingarm, being rigid and of one piece with the socket, will strike againstportions of the gas-fixture adjacent to the nipple, and thus preventturning the socket, so as to screw it into place, whereas, in myinvention, the socket B, being a separate piece, can readily be screwedonto the nipple of any gas fixture, then the eye of the arm adjustedabout its neck, so the arm will stand as nearly in the directionrequired as the an-' 0 and nipple b, and the arm, as D, one end of whichis provided with a nipple adapting it to attach a lamp and the other endwith an angular opening or eye adapted to fit the neck of said socket,combined and arranged in the manner and for the purpose specified.

In testimony that I claim the foregoing as my invention'l have signedmyname, in presence of two witnesses, this 6th day of June, 1888.
